Normal Vital Signs — School-age (6–12 years)

School-age children have the widest span in this chart — a small 6-year-old and a nearly teenage 12-year-old differ a lot, so treat the ranges as a band rather than a single target. Blood pressure in particular climbs steadily with height and age across these years, which is why clinicians plot it on charts for the individual child.

Vital signNormal range — school-age (6–12 years)
Heart rate (awake, resting)70–120 beats/min
Breathing rate18–25 breaths/min
Blood pressure — systolic100–120 mmHg
Blood pressure — diastolic60–80 mmHg
Oxygen saturation (SpO2, room air)95% or higher
Body temperature97.5–99.3 °F (36.4–37.4 °C)

◆ Good to know

Use a correctly sized blood-pressure cuff — a cuff that is too small makes the reading falsely high, which is a common cause of a surprising result at this age.

Measuring at this age

  • Blood pressure: right cuff size, arm supported at heart level, feet flat, no talking, after five quiet minutes.
  • Resting heart rate is best first thing in the morning or after sitting quietly — not straight after sport or gaming excitement.
  • Count breathing unobtrusively for a full minute; children this age often hold or change their breath if they notice.

Fever at this age

A temperature of 100.4°F (38.0°C) or higher is a fever. Thresholds, measuring methods and warning signs by age are covered in the fever guide — and any fever in a baby under 3 months old needs medical care the same day.

The full eight-band chart is on the vital signs by age hub, and as a printable wall chart.

Please note: This page is patient education, not medical advice. Normal ranges are guides for a person who is awake, resting and measured correctly — a single reading outside the range is not a diagnosis. Abnormal readings in someone who is unwell, breathing with difficulty, unusually drowsy or simply worrying you warrant medical care — seek it promptly rather than re-checking at home.
